A study of the impact of a High Pressure Sodium (HPS) lamps on power quality

Discharge lamps based on plasma emitting light are the most important electric light sources. They are used in virtually all areas of modern lighting technology and they are produced in wide range of powers with different levels of luminous efficacy. The main concern of lighting systems is their impact on power quality. The study proposed in this work is to measure power factor and harmonic disturbances generated by a 250W HPS lamp with magnetic ballast. An experimental setup is carried out to study the harmonic impact of large scale deployment of HID lamp. In addition, results obtained for these lamps are compared with those obtained for Compact Fluorescent Lamps (CFLs) widely used by electricity consumers in modern lighting and a simulation is also conducted using conductance model of High Intensity Discharge lamp.
